Author Topic:   Outrage 22 Fuel Tank Cavity

mcorelli posted 01-05-2004 07:28 PM ET (US)
I am in the process of shopping for a classic 22 Outrage and noticed that on one there was a gel or slime material on top of the fuel tank when the inspection plate on the deck was removed. What is it? Can it be washed off? I am concerned as to where the water goes if it should enter the fuel tank compartment.

I try not to look into my inspection plate. I hear growling under there! Do a search and you'll find all you need to know about the subject. Happy New Years fellow whalers!

If you fuel tank has a slimy growth on the top surface it probably acquired it after it left the factory.
Water that enters the central cockpit fuel tank cavity is intended to be contained on the top of the tank or on the foam that surrounds the tank. If the bond between the foam and the tank or the cavity walls has loosened, water could soak into the bottom of the cavity. The cavity is not drained at the bottom. Some drains near the top of the cavity allow water to escape from the upper levels. Entrapped water sitting on the tank surface leaves by evaporation.
I recommend leaving the tank cavity access plates off when storing the boat to encourage evaporation. This assumes the boat is protected from rain entering the cockpit and draining into the cavity.

See http://continuouswave.com/whaler/cetacea/cetaceaPage70.html to get an idea of what lurks beneath the floor of a 22 foot Whaler hull. The Revenge hull is pretty much the same as the Outrage, with minor changes made to both over the years they were in production.

Thank you all for your input. I read and reviewed the article on the 22 Revenge, but still wasn't sure as to where the water would go if the top of the tank was washed off. From the pictures it appears that it would eventually go into the fuel line troughs along the outer sides of the tank. Has anyone been successful in cleaning off the top of the tank without removing the floor?

my Outrage 20 had some green slim on the top of the tank also. I wouldn't wash it off as the water doesn't drain from the tank cavity. There is a drain, per se, but its at the top of the cavity and not the bottom so you'll always have about 10-14 gallons of water in there from reports I've heard when people have replaced their fuel cells. Sorry for the cliche but I've got to remind myself of it often: if it ain't broke, don't fix it. Best wishes.
